List of Mattel doll, clothing and accessories designers 1-4

With little to do, I have been researching and compiling the names of the designers who created which Barbie and family dolls, outfits and accessories.  Of course these lists aren't everything--I doubt Mattel ever kept accurate records on that!--just the ones I've found written about.  My information comes from various Barbie reference books, Mattel biographies and articles in Barbie Bazaar.
Here are lists one, two, three and four.
